Metro coaches lifted, placed on elevated track

New Delhi: For the first time in its
history, DMRC lowered four Metro coaches on to the tracks at
Lajpat Nagar station where they will be assembled before the
trial runs on the Central Secretariat-Badarpur line begin in
the first week of July.

The coaches, which were brought through trailers from
the Mundka Standard Guage depot, were lowered on the inclined
ramp between Jangpura and Lajpat Nagar by using a 270 tonne
crane, which was equipped with a special adjustable boom which
helped in quick stabilisation of the coaches on the track.

The coaches, each weighing 42 tonnes, were lowered one
after another during the operation which started at around 11.00
pm last night and ended at 4.10 am today, DMRC spokesman Anuj
Dayal said.

The 20.16-km Central Secretariat-Badarpur corridor will
be thrown open to the public in September, a month ahead of
the Commonwealth Games.

DMRC had to lower the trains at the Lajpat Nagar station
as there is no other way that the coaches can be brought to
the station.

Trial runs on the Central Secretariat-Badarpur Standard
Guage line will start in phases from July first week and will
go on till the line is thrown open to the public in September,
a month before the Commonwealth Games.

DMRC officials said the lowering of trains were a
peculiar move since they do not have any other entry point.

The coaches will now be assembled on tracks at the Lajpat
Nagar station and the trial runs will begin after July 5 from
Central Secretariat-Lajpat Nagar section once the signalling
and other works are completed on the 9-km section.

"The operation was a great engineering achievement as
the coaches were stabled on a gradient (inclined) of about 4
per cent. Generally, the rail coaches are stabled on a
straight surface," Dayal said.

Two battery operated shunters were used to prevent the
coaches from sliding down backwards on the incline. These
shunters then pushed the coaches to the Lajpat Nagar Metro
station where the coupling will be done, he said.

The entire exercise will help the DMRC save at least a
month`s time to meet its Commonwealth Games deadline.

This was the first-ever operation in India where Standard
Gauge Metro rail coaches were lifted by cranes and stabled on
the inclined tracks, he said.

"Meticulous planning of over six months was done to
implement the operation smoothly. All Cargo, a specialised
agency was roped in to carry out the operation. About 400
people including DMRC engineers worked round the clock to
implement the operation successfully," Dayal said.
